  • Patent number: 8677001
    Abstract: A data processing apparatus edits an actual data portion excluding a header from data transmitted by streaming transmission from a first information processing apparatus after start of streaming transmission. The data processing apparatus transmits edited actual data portion and header to a second information processing apparatus by streaming transmission. The second information processing apparatus reproduces the voice data or the animation data transmitted by streaming transmission. The actual data portion is edited so that the voice data or the animation data to be transmitted may be reproducible in the second information processing apparatus, and so that a program may become unexecutable even if it would be transmitted to the second information processing apparatus.

  • Patent number: 8611206
    Abstract: A loss determining unit of a monitoring device calculates a receiving-time interval between a receiving time of data and the receiving time of immediately previous data. If the interval is a predetermined threshold or higher, the loss determining unit determines that “a loss is detected” and calculates the number of losses. If the number of losses is lower than the threshold, the loss determining unit determines that “no loss is detected”. A failure-section determining unit calculates the number of losses occurring in a first section. The failure-section determining unit calculates the number of losses occurring in a second section. If the loss is detected in the first section, the failure-section determining unit determines that a failure occurs in the first section. If the loss is detected in the second section, the failure-section determining unit determines that a failure occurs in the second section.

  • Patent number: 8605617
    Abstract: A sharing control processing unit controls sharing of capture of packets among measuring devices connected to the same network. An aggregating unit collects the captured packets. Each measuring device notifies the sharing control processing unit of a state about its capture. The sharing control processing unit determines which measuring device is to start/stop the capture, according to a predetermined rule and the notified state. When determining that the capture is to be switched from a first measuring device to a second measuring device, the sharing control processing unit instructs the second measuring device to start the capture. After receiving a notification that the second measuring device has actually captured a packet(s), the sharing control processing unit instructs the first measuring device to stop the capture. The aggregating unit identifies a duplicate packet(s) double captured by the first and second measuring devices.

  • Patent number: 8593974
    Abstract: A communication conditions determination method, a communication conditions determination system, and a determination apparatus are provided in which the conditions of communication which is performed through a plurality of communication networks are determined without setting up a special apparatus on all the communication networks and without increasing the existing traffic. In a first communication network 100 and a second communication network 200 which are connected by a first connection apparatus 1 such as a router, a determination is made as to whether the source of a packet passed through the second communication network 200 is the first connection apparatus 1 or an apparatus other than the first connection apparatus 1. Packets whose respective sources are the first connection apparatus 1 and packets whose respective sources are an apparatus other than the first connection apparatus 1 are individually summarized. By comparing summarized results, the communication conditions are determined.

  • Patent number: 8547858
    Abstract: A communication-quality measuring method disclosed in the present invention acquires packets to be transferred in a packet switching network and accumulates the acquired packets in an internal buffer. An acquisition amount indicating an amount of packets acquired per given unit time, a loss amount indicating an amount of packets lost during transfer in the packet switching network, and an acquisition leak amount indicating an amount of packets that cannot be accumulated in the internal buffer out of the acquired packets are measured. Based on the measured acquisition amount, loss amount, and acquisition leak amount, a packet loss rate transferred in the packet switching network and an error for the loss rate are calculated and the calculated loss rate and the loss rate error are output.
